[0047] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0048] The present application aims to at least solve the technical problem of mechanical processing lines formed near the drain outlet in the related art. To this end, the present application proposes a frame that can alleviate the influence of mechanical processing lines near the drain outlet to a certain extent.

[0049] Reference below Figure 1-Figure 11 A frame 1 according to an embodiment of the present application is described.

[0050] like Figure 1-Figure 4 As shown, the frame 1 includes: a plurality of side beams 10, the side beams 10 are hollow structural members, and at least one side beam 10 has a notch 120 at the end thereof at the bottom plate, and the side beam 10 where the notch 120 is located is connected to an adjacent side beam 10 to form a drainage outlet 130 at the notch 120.

[0051] The frame 1 can protect the laminate of the photovoltaic module from external physical impact and damage, and can also provide necessary support for the laminate so that it can withstand external loads such as wind pressure and snow pressure to maintain the normal operation of the module.

[0052] like Figure 2 As shown, a notch 120 is provided at the bottom plate of the end of the side beam 10, and a drainage port 130 is formed with the adjacent side beam 10, which can effectively drain the moisture accumulated inside the frame 1, reduce the erosion and damage of the moisture to the laminate, thereby improving the weather resistance and service life of the photovoltaic module. The notch 120 is stamped.

[0053] like Figure 1 As shown, the frame 1 can form an integral structure by connecting a plurality of side beams 10 end to end in sequence, thereby enhancing its structural strength and stability, so that the frame 1 can better withstand external loads and protect the laminate from damage. In addition, through reasonable connection methods and structural designs, the installation process can be simplified, the installation cost can be reduced, and the frame 1 components can be easily disassembled and replaced.

[0054] The number of drain outlets 130 of the frame 1 can be one or more, depending on the application scenarios. For example, when the photovoltaic component is fixedly installed, one drain outlet 130 can be set, and when the photovoltaic component is rotatably installed, multiple drain outlets 130 can be set.

[0055] The fixed installation of photovoltaic modules is suitable for stable power generation scenarios. For example, fixed photovoltaic modules are usually installed on roofs, ground, walls and other locations, and are firmly fixed to the installation surface by brackets, bolts and other fixings. Fixed photovoltaic modules will not be displaced or tilted due to natural factors such as wind and rain, and the number of drainage outlets 130 is not required.

[0056] The rotating installation of photovoltaic modules is suitable for complex terrain scenarios. For example, rotating photovoltaic modules are usually installed on mountains, hills or sloping roofs. The angle and orientation of the photovoltaic modules are automatically adjusted to maximize the capture of solar radiation. The rotating photovoltaic modules are in a tilted state for a long time, and a high number of drainage outlets 130 are required to ensure smooth drainage.

[0057] For example, drainage holes 130 are provided at the connection points of the side beams 10 of the frame 1. When the photovoltaic module rotates, the connection point of the side beams 10 at the lowest point is not fixed, but each connection point of the side beams 10 is provided with a drainage hole 130, and normal drainage can be achieved through the drainage hole 130 at the lowest point.

[0058] In the related art, water is easily accumulated in the cavity of the frame of the photovoltaic module, and a drainage hole is usually processed at the bottom of the cavity to drain the water in the cavity. The frame is made of aluminum alloy, and the drainage hole is usually a stamping design. However, there is no support for the stamping surface in the cavity of the conventional photovoltaic frame. When punching the drainage hole, due to the stamping action of the stamping mold, mechanical processing lines are easily formed around the drainage hole, causing the periphery of the drainage hole to bulge inward, affecting the drainage effect, and further affecting the yield of the product. There is room for improvement. The present application punches a notch 120 at the end of the bottom wall of the cavity 110 of the side beam 10 to solve the problem of mechanical processing lines being formed near the notch 120 due to the lack of support on the stamping surface when the notch 120 is stamped.

[0059] According to the frame 1 provided in the embodiment of the present application, by setting the notch 120 at the bottom plate of the end of the side beam 10, a tool can be used to provide support for the stamping surface when stamping the notch 120, thereby alleviating the influence of the machining marks near the notch 120 to a certain extent and improving the structural integrity and drainage efficiency of the frame 1.

[0060] In some embodiments, Figure 4 and Figure 5 As shown, the side beam 10 forms a cavity 110 , and the cavity 110 includes: a main cavity 111 and a drainage groove 112 . The drainage groove 112 is provided below the bottom wall of the main cavity 111 , and the notch 120 is provided at the bottom of the drainage groove 112 .

[0061] The side beam 10 forms a cavity 110, and the cavity 110 includes a main cavity 111 and a drainage groove 112. The drainage groove 112 is connected to the main cavity 111 but is relatively independent. The main function of the drainage groove 112 is to collect and discharge moisture accumulated inside the cavity 110 of the frame 1. By setting the drainage groove 112 below the bottom wall of the main cavity 111, the moisture can be effectively guided into the drainage groove 112, thereby reducing the direct contact and damage of moisture to the laminate.

[0062] The notch 120 is set at the bottom of the drainage groove 112. When a certain amount of water accumulates in the drainage groove 112, the water can be discharged smoothly through the notch 120. The notch 120 can be designed into a triangle or other shape to guide the water flow and improve its discharge efficiency. For example, the sharp bottom of the triangle can reduce the resistance of the water flow during the discharge process, allowing the water to flow out more smoothly.

[0063] It can be understood that subdividing the cavity 110 into the main cavity 111 and the drainage groove 112 and providing a notch 120 at the bottom of the drainage groove 112 can efficiently drain the moisture inside the frame 1, protect the laminate from damage, and improve the structural stability and maintenance convenience of the frame 1.

[0064] In some embodiments, Figure 6 and Figure 7 As shown, the cross-section of the drainage groove 112 has various structural forms, including but not limited to:

[0065] In example 1, the cross-section of the drainage groove 112 is in a rectangular shape.

[0066] like Figure 6As shown, the drainage groove 112 extends along the length direction of the side beam 10, and the cross-sectional shape can be a rectangle. The rectangular cross-sectional shape is simple, and can provide a stable drainage channel to meet the drainage needs in most cases. The rectangular structure is relatively stable and can withstand a certain external pressure. When the frame 1 is subjected to a load, the rectangular drainage groove 112 can maintain its shape and stability. In addition, the processing of the rectangle is relatively simple, and can be easily achieved through cutting, stamping and other processes, which helps to reduce the production cost of the frame 1 and improve production efficiency.

[0067] Example 2: The cross-section of the drainage groove 112 is in the shape of an inverted trapezoid.

[0068] like Figure 7 As shown, the drainage groove 112 extends along the length direction of the side beam 10, and the shape of the cross section can be an inverted trapezoid. Compared with the rectangle, the inverted trapezoidal cross-sectional shape has better drainage performance, and its upper end is wider than the lower end. When water flows into the drainage groove 112, it will be restricted by the gradually shrinking channel, thereby accelerating the flow and being discharged smoothly. It is suitable for scenes that require efficient drainage. The inverted trapezoidal shape also has a certain self-cleaning ability. During the drainage process, the water flow will flow downward along the groove wall, carrying away attached impurities and dirt, thereby reducing the risk of clogging of the drainage groove 112.

[0069] It is understandable that in actual applications, a suitable shape of the drainage groove 112 can be selected according to specific needs and conditions.

[0070] In some embodiments, Figure 5 As shown, the side beam 10 is provided with a clamping portion 140 for clamping the laminate, and the clamping portion 140 is located at a side of the main cavity 111 away from the drainage groove 112 .

[0071] The main function of the clamping portion 140 is to firmly clamp the laminate to reduce its movement or falling off inside the frame 1, so as to improve the stability and safety of the photovoltaic module. The clamping portion 140 can also protect the laminate. Through reasonable clamping force and method, the damage to the laminate when subjected to external impact or vibration can be reduced. At the same time, the clamping portion 140 can also have the function of improving the heat dissipation performance. By optimizing the structure and material selection of the clamping portion 140, the heat exchange between the laminate and the external environment can be promoted, thereby reducing the working temperature of the laminate and improving its working efficiency and life.

[0072] In addition, the main function of the drainage groove 112 is drainage. Disposing the clamping portion 140 on the side away from the drainage groove 112 can reduce the interference of the clamping portion 140 on the drainage efficiency of the drainage groove 112, and also help to optimize the overall structural layout of the frame 1, that is, the clamping portion 140 and the drainage groove 112 are respectively located on both sides of the main cavity 111, each assuming different functions, which can make the structure of the frame 1 more compact.

[0073] It can be understood that the clamping portion 140 is located on the side of the main cavity 111 away from the drainage groove 112, which can reduce the impact on the drainage groove 112 and can also stably clamp the laminate.

[0074] In some embodiments, Figure 2 and Figure 4 As shown, the butt joint of the notch 120 has various structural forms, including but not limited to:

[0075] At least one end of the bottom wall of the cavity 110 of the side beam 10 is provided with a notch 120, and multiple side beams 10 are connected end to end in sequence, then two connected ends of adjacent side beams 10 are provided with at least one notch 120, wherein the notch 120 is triangular, and the drain outlet 130 can be triangular or rectangular.

[0076] In example 1, the notch 120 and an adjacent side beam 10 form a drain port 130 , and the drain port 130 is in a triangular shape.

[0077] like Figure 4 As shown, the end of the bottom wall of the cavity 110 of the side beam 10 is provided with an angle, and the angles of the adjacent ends of the bottom walls of the cavities 110 of two adjacent side beams 10 connected end to end are complementary to each other, so that the two adjacent side beams 10 form a vertical relationship during assembly, and the notch 120 is a right triangle and corresponds to the angle of the end.

[0078] In this embodiment, the drain outlet 130 at the connection between two adjacent side beams 10 connected end to end is formed by a notch 120, and the shape of the drain outlet 130 is the same as the notch 120, that is, the connection end of one of the side beams 10 is provided with a notch 120, and the connection end of the other side beam 10 may not be provided with a notch 120, and the hypotenuse of the triangular notch 120 and the end of the other side beam 10 form the drain outlet 130.

[0079] In the second example, the adjacent notches 120 of the adjacent side beams 10 are butted together to form a drainage opening 130 , and the drainage opening 130 is rectangular.

[0080] like Figure 2 As shown, the end of the bottom wall of the cavity 110 of the side beam 10 is provided with an angle, and the angles of the adjacent ends of the bottom walls of the cavities 110 of two adjacent side beams 10 connected end to end are complementary to each other, so that the two adjacent side beams 10 form a vertical relationship during assembly, and the notch 120 is a right triangle and corresponds to the angle of the end.

[0081] In this embodiment, the drain outlet 130 at the connection between two adjacent side beams 10 connected end to end is formed by two notches 120, and the shape of the drain outlet 130 is rectangular, that is, the connecting ends of the two adjacent side beams 10 are each provided with a notch 120, and the hypotenuse of the triangular notch 120 is aligned with the hypotenuse of the other notch 120 to form a rectangular drain outlet 130.

[0082] It is understandable that the shape of the drain port 130 can be selected according to the specific installation environment and drainage requirements.

[0083] like Figure 4 As shown, the triangular notch 120 has a sharp bottom, which helps the water accumulated inside the frame 1 to flow out more smoothly along the edge of the triangle when it reaches a certain amount. The triangular shape can also keep the water flow at a high speed during the discharge process, thereby improving the drainage efficiency. When adjacent triangular notches 120 are connected, they can form a larger drainage port 130 together to effectively guide the rapid discharge of water.

[0084] The stability of the triangle can provide additional support and stability when the frame 1 is subjected to external pressure. The processing of the triangular notch 120 is also relatively simple, and can be easily achieved through processes such as cutting or stamping, thereby reducing the production cost of the frame 1 and improving production efficiency. At the same time, the regular shape of the triangular notch can make the frame 1 easier to operate during installation and docking, reducing the difficulty and time of installation.

[0085] The drain outlet 130 can be designed to be triangular or rectangular, and the most suitable shape of the drain outlet 130 is selected mainly according to the specific installation environment and drainage requirements. For example, when a larger drainage area is required, a rectangular drain outlet 130 can be selected, and when space is limited or a higher drainage speed is required, a triangular drain outlet 130 can be selected.

[0086] It can be understood that the triangular notch 120 can take into account both the drainage function and the structural stability of the frame 1, which helps to enhance the overall structural strength of the frame 1. In addition, the triangular notch 120 is convenient for providing a support surface during stamping, which can alleviate the impact of machining marks near the drainage hole to a certain extent.

[0087] In some embodiments, Fig. 9 and Fig.10 As shown, the frame 1 further includes: an angle code 20 , which is connected between two adjacent side beams 10 and extends into the cavity 110 , and is supported on the bottom wall of the main cavity 111 .

[0088] The corner code 20 is a connecting piece between two adjacent side beams 10 and is mainly used to tightly connect the adjacent side beams 10 together to form a complete frame 1 structure. This connection method enables the frame 1 to jointly bear the force when subjected to external loads, thereby improving the overall rigidity and stability of the frame 1.

[0089] Extending the corner code 20 into the cavity 110 and supporting it on the bottom wall of the main cavity 111 can provide an additional support point for the frame 1. This support can enhance the load-bearing capacity of the frame 1 and reduce deformation or damage caused by long-term bearing of the weight of the laminate and external pressure. When the photovoltaic module is subjected to external loads, the corner code 20 can also disperse and transfer stress to various parts of the frame 1, which helps to reduce the occurrence of local stress concentration and reduce the risk of damage to the frame 1 due to excessive stress.

[0090] The corner code 20 is usually made of high-strength and corrosion-resistant materials, such as aluminum alloy or stainless steel. The good mechanical properties and weather resistance can meet the use requirements of the photovoltaic module frame 1. The corner code 20 is tightly connected and stably supported with the side beam 10 through multiple connection points and supporting surfaces.

[0091] It can be understood that the corner code 20 is connected between two adjacent side beams 10, extends into the cavity 110 and is supported on the bottom wall of the main cavity 111, which can enhance the overall structural strength of the frame 1 and improve the stability and durability of the photovoltaic module.

[0092] In some embodiments, Figure 8 As shown, at least one side of the bottom wall of the main cavity 111 is provided with a convex edge 113 protruding toward the notch of the drainage groove 112 , and the convex edge 113 is flush with the bottom wall of the main cavity 111 .

[0093] The corner code 20 is supported on the bottom wall of the main cavity 111, and a convex edge 113 protruding toward the notch of the drainage groove 112 is provided on at least one side of the bottom wall of the main cavity 111, which can provide an additional support point for the corner code 20 and increase the contact area between the corner code 20 and the bottom wall of the main cavity 111. When the frame 1 is subjected to external pressure or impact, the convex edge 113 can help the corner code 20 to disperse and withstand part of the impact, thereby reducing the stress concentration phenomenon of the bottom wall, helping to enhance the overall structural strength of the frame 1 and improve its ability to resist deformation and damage.

[0094] The convex edge 113 protrudes toward the notch of the drain groove 112 and can also form a natural guiding channel between the bottom wall and the drain groove 112. When the moisture accumulated inside the frame 1 needs to be discharged, the moisture will more easily flow along the convex edge 113 to the notch of the drain groove 112, thereby accelerating the drainage process. In addition, the design of the convex edge 113 being flush with the bottom wall of the main cavity 111 can improve the smoothness of the drainage process and reduce drainage obstacles caused by height differences.

[0095] It can be understood that the convex edge 113 provided on the bottom wall of the main cavity 111 can enhance the structural strength of the frame 1 and optimize the drainage performance.

[0096] In some embodiments, Fig.11 As shown, the angle bracket 20 includes an inner plate 210, an outer plate 220 and a connecting rib 230 connected between the inner plate 210 and the outer plate 220. The inner plate 210 of the angle bracket 20 is provided with a serrated structure.

[0097] The inner plate 210, the outer plate 220 and the connecting rib 230 together constitute the main supporting structure of the angle bracket 20, which can provide sufficient strength and rigidity for the angle bracket 20, and can also enable the angle bracket 20 to maintain a stable shape and size when connected to the side beam 10. The inner plate 210 and the outer plate 220 are both close to the side wall of the cavity 110 of the side beam 10 to provide support and fixation. The design of the connecting rib 230 helps to optimize the stress distribution inside the angle bracket 20. When subjected to external loads, the connecting rib 230 can disperse the stress to the entire structure of the angle bracket 20, reduce the occurrence of local stress concentration, and thus improve the durability and service life of the angle bracket 20.

[0098] The serrated structure on the inner plate 210 can increase the friction of the contact surface between the corner bracket 20 and the side beam 10, thereby improving the connection strength between the corner bracket 20 and the side beam 10, so that the corner bracket 20 can be more firmly fixed on the side beam 10 when subjected to external loads, reducing the risk of loosening or falling off. The serrated structure also has a certain elastic deformation ability, which can absorb and disperse vibration energy to a certain extent, thereby improving the seismic performance of the frame 1 and reducing damage to the frame 1 and the risk of falling off of the laminate.

[0099] It is understandable that the angle code 20 adopts a structural design of an inner plate 210, an outer plate 220 and a connecting rib 230, and a serrated structure is provided on the inner plate 210, which can enhance the connection strength between the angle code 20 and the side beam 10 and optimize the stress distribution.

[0100] The embodiment of the present application further provides a photovoltaic assembly, comprising: a laminate and a frame 1 , wherein the laminate is mounted on the frame 1 .

[0101] The laminate is the core part of the photovoltaic module, which is usually composed of photovoltaic panels, transparent front covers, back panels and packaging materials. It is responsible for converting light energy into electrical energy. These materials are processed through a special lamination process to form an integral structure. It not only has excellent power generation performance, but also has good weather resistance and mechanical strength, and can work stably for a long time in various harsh environments.

[0102] The frame 1 is the supporting and protective structure of the photovoltaic module, and is usually made of metal materials or composite materials such as aluminum alloy and stainless steel. It can enhance the overall structural strength of the photovoltaic module and improve its compressive resistance. It can also integrate a drain port 130 to remove water accumulation inside the frame 1 and reduce damage to the laminate caused by water immersion.

[0103] The installation between the laminate and the frame 1 is usually carried out in a variety of ways, such as gluing, snap connection, etc., so that the laminate and the frame 1 are tightly fitted and firmly connected during the installation process to reduce loosening or falling off during subsequent use.

[0104] It can be understood that by firmly fixing the laminate in the frame 1, a complete and reliable photovoltaic module can be formed, which can meet the needs of various photovoltaic power generation systems.
